Brake pad product notes: Shims and Wear sensors Our brake pad products are designed for high performance and competition use. Therefore, we do not always provide ancillary parts such as wear sensors or anti-squeal shims on some of the range including WinmaX and CIRCO. Ancillary parts are provided in some cases depending on the pad specification and fitment. NRS Brakes are designed to be OEM replacement and will be supplied with all components expected for road use. If you are unsure about any of this, please contact the seller for confirmation. Fitment FRONT, REAR or UNIVERSAL? Our brake pad products are engineered to replace OEM parts with higher performance friction. Many pad shapes are designed to be installed in only front or rear. However, there are many pad shapes in the Automotive world that are shared across multiple makes and models. In many cases these shapes are installed in the front on one vehicle, but the same shape is used in the rear of another. In some cases, the same pad shape is used in both front AND rear. If a brake pad is known to be used for front and/or rear, we refer to it as UNIVERSAL. If unsure about the fitment when purchasing, please check with the seller.
